* Bug: In Bootstrap, in coriolisEnv.py, check if devtoolset-2 is already
active before launching it as a sub-shell.
* Bug: In Isobar, In PyHurricane.h, DBoDestroyAttribute() set the proxy
pointer toward the C++ object to NULL. So when the Python object is
deleted no double-deletion occurs on the C++ object.
Add some more trace information in Python link/dealloc.
* Change: In CRL Core, in cyclop, make CMakeLists.txt automatically
choose the right rule for linking the binary wether we use Qt 4 or
Qt 5. Very irksome problem.
* New: In EtesianEngine::addFeed(), do not take into account instances
that are not placed entirely inside the top cell abutment box (was
causing a core dump).
* Bug: In Katabatic, in GCellQueue, correct a mismatch between a GCell
set and the iterators used upon it.
* Bug: In Mauka, in Row & Surface correct a mismatch between a container
and it's iterator.
* New: In Etesian, updated to work with the latest Coloquinte, patch
contributed by G. Gouvine.
Added EtesianEngine::setDefaultAb() to compute an abutment box if
the Cell is completly unplaced.
* New: In cumulus, in ClockTree, now the placer can be configured to be
either Mauka (slow simulated annealing) or Etesian (fast analytic).
New setting 'clockTree.placerEngine' in plugin settings.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
The sub-directory name is 'el7_64'.
In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
doing it (or not).
* New: In CRL Core, in helpers & alliance.conf, set and read a "PAD"
variable to define the pad model name extension ("px" for "sxlib
and "pxr" for vsxlib, this is provisional).
* New: In CRL Core, in plugin.conf, add parameters to define the name
of used for power & clock supply. We may remove the extention in
the future (to be more coherent with the previous modification).
* New: In Cumulus, in chip.Configuration.GaugeConf._rpAccess(), no
longer place the accessing contact *at the center* of the
RoutingPad. It works under sxlib because buffers & registers all
have same size terminals. But this is not true under vsxlib,
leading to misaligned contacts & wires. Now systematically place
on the slice midlle track (maybe with one pitch above or below).
This is still very weak as we do not check if the terminal
reach were the contact is being put. Has to be strenthened in
the future.
* New: In Cumulus, in chip.Configuration.ChipConf, read the new
clock & power pad parameters.
* Change: In Isobar (and all other Python wrappers), uses PyLong instead
of PyInt for DbU conversions. In PyHurricane argument converter,
automatically check for both PyLong and then PyInt.
* Change: In Cumulus, in chip.PadsCorona, more accurate error message
in case of discrepency in global net connections (i.e. no net
of the same name in instance model and instance model owner.
* Change: In Kite, in BuildPowerRails, when looking up at the pads
model name to find "pck_" or "pvddeck_", do not compare the
extension part. But we still use hard-coded stem pad names,
maybe we shouldn't.
* Bug: In Katabatic, in GCellConfiguration::_do_xG_xM1_xM3(), there
was a loop in the search of the best N/E initial RoutingPad.
* Bug: In Kite, in KiteEngine::protectRoutingPads(), *do not* protect
RoutingPads of fixed nets, they are already through the
BuildPowerRails stage (and it's causing scary overlap warning
messages).
* Bug: In Cumulus, in ClockTree.HTreeNode.addLeaf(), do not create
deep-plug when the core is flat (not sub-modules). All the new
nets are at core level.
* Bug: In Cumulus, in ChipPlugin.PlaceCore.doFloorplan(), ensure
that the core is aligned on the GCell grid (i.e. the slice
grid of the overall chip).
* Bug: In Kite, in GCellTopology::_do_xG_xM1_xM3(), infinite loop
while looking for the bigger N-E RoutingPad. Forgot to decrement
the index...
* New: In ClockTree plugin, select the name of the buffer cell through
configuration (parameter: "clockTree.buffer"), and guess the I/O
name of this buffer automatically.
Put configuration parameters in plugin.conf and not mauka.conf.
Bug: strangely triggers a coredump in components collection
when used with <vsxlib>. Some debug printing still active until
that is solved.
* New: In Chip plugin, make the size and numbers of the block rails
configuration parameters (in plugin.conf).
Finally get rid of the demonic code from Wu Yifei...
* New: In Isobar, added encapsulation of Interval (don't know how have
forgotten it for so long).
* Change: In Isobar, In PyLayer, new PyLink_LayerDerived() function to
create/link the C++ object to the correct derived class and not the
base one (PyLayer) which then prevent to use the specialized methods.
Must replace PyLink_Layer() througout all the code.
* Change: In Isobar, in PyPoint the "setX()" & "setY()" methods where
still capitalized.
* Change: In Isobar, in PyQuery, complete the exportation of the C++
interface. remove the code belonging to a more "boost" way of
building the Python interface (will do that in a far future).
* New: In CRL Core, In PyAllianceFramework, export isPad() method.
* Change: In Unicorn, in unicornInit.py, protect the loading of each
single plugin by a "try" / "except" clause to the failing of one
plugins do not stop the loading of the next one.
Pass the same dictionnary argument to unicornHook() as for
ScripMain(), this is more uniform this way.
* New: In Cumulus, complete replacement of the chip placement scripts
from Wu Yifei (at last!). The clock-tree integration is still to
be done.
